Degrees of degrees - public vaping

I have seen debates on forums about vaping around children/in public places where genuine ITK vapers stand against this activity.

What?

Really?!

We are talking about minutae here people. IF there is anything harmful in the vapour we expel it is so infinatessimally small in quantity so as to make it entirely negligible in this modern world of traffic, factory and natural pollutants.

I vape around my kids because it is so much better than smoking around them. They know not to touch it and it has normalised it in their minds. If they choose to smoke in the future I would much rather they chose a funky mod than a pack of marlboro.
